STU

Who is STU

STU is a brawler of Epic rarity, class Assassin. This article summarizes their performance in the current competitive meta: best map, hardest counters, and the weekly trend of their win rate. The numbers come from top-PRO battles over the last 90 days, Bayesian-smoothed so a brawler with a small sample doesn't show a misleading percentage.

Over the 30-day window, STU has shown up in 1,690 battles with a global win rate of 65.4%. That window belongs to the figure itself and is shorter than the one feeding the rest of the page, because a win rate needs recent data so it doesn't drag along a meta that already moved on.

Across the full 90 days, STU has a pick rate of 1.0%. That pick rate is the share of matches where a top-PRO player chose STU out of every available brawler, so it works as a thermometer for how meta they are right now. It uses the long window on purpose, because a brawler's popularity shifts more slowly than their win rate.

Across the full roster, STU's trend is among the strongest: their win rate is climbing faster than 95% of brawlers with a measurable trend this week. When a brawler rises this fast it's usually because maps or modes rotated in where their kit fits better than average.

The two figures for STU tell different things. The observed win rate, 65.4%, measures how often it wins in the hands of a top 200 player from its country. The discounted strength, 43.7%, estimates how often it would win against a mid-level opponent once the mix of opponents it happened to face is discounted. The first one orders the lists across the site and the second sits beside it, as context.

By discounted strength, STU takes rank 79 of 107, in the bottom third of the roster. Its observed win rate leans in part on the opponents it happened to face, so read it together with the specific map and mode.

STU is an Epic brawler, a rarity where kits start to break conventions: unique mechanics, supers with special effects and gadgets that flip the whole game plan. The gem or Starr Drop investment is steeper, but in return you get a tool that defines entire lanes in draft and tends to be picked in tournaments whenever its signature map enters rotation.

As an Assassin, the pattern is aggressive burst: lean on the kit mobility to flank, eliminate a priority target and exit before the counter-attack lands. Super economy is critical because most assassins rely on it to escape after the pick. Maps with walls and blind angles amplify the playstyle; open maps punish it severely.

Best maps for STU

The best map for STU is Under Pressure in Hot Zone, with a Bayesian-adjusted win rate of 83.4% over 52 battles. That puts them above their class average in this mode, so it's worth picking STU when that rotation is live. A strong run on Under Pressure usually combines favorable geometry (short ranges or cover) and a mode whose objective plays into the brawler's kit.

STU's performance is highly map-dependent: there are 31.0 percentage points between their best and worst map. That high variance means it pays to check the rotation before locking them in, because the same brawler swings from one of the best options to a clearly unfavorable pick depending on the map.

As a second map option, STU also performs well on Cabin Fever (Brawl Hockey) with a 80.2% win rate, only 3.3 points off their best map. When the gap between the top two maps is this small, picking one over the other comes down to the enemy team more than the brawler itself.

Rounding out the podium, STU holds a 76.4% win rate on Healthy Middle Ground (Knockout) over 36 battles. Having three competitive maps widens the rotation windows worth bringing them in for, not just their signature map.

Just above their worst result, STU also struggles on Pump It Up, where their win rate sits at 58.7%. Keep this map on your radar as a second warning sign when deciding the pick.

On the opposite end, Sneaky Fields (Brawl Ball) drops STU's win rate to 52.5%. That's the bottom tail of a 31.0-point range between their best and worst map, so if that rotation comes up during a session, consider a different brawler to avoid throwing matches.

Counters and matchups

STU clearly dominates the matchup against TICK: across the 124 recorded battles for that pairing, their win rate climbs to 80.8%. If you spot TICK on the enemy team in draft, that lane is an edge for STU — seek the duel out rather than avoid it.

Their second-best matchup is against EDGAR, where STU holds a 77.4% win rate over 194 battles. Two strong favorable counters like these give STU real value as a targeted pick against comps that lean on those two brawlers.

Where STU has a clear disadvantage is against GUS: their win rate drops to 48.5% across the 181 battles recorded for that matchup. If GUS shows up on the enemy team, consider not picking STU or changing the game plan to avoid the shared lane, because GUS wins that exchange.

Per-brawler matchups are the smallest-sample metric on the page: for STU the samples range from 31 to 194 battles. Read them with the confidence that sample implies — a matchup at the low end says far less than one backed by the high one.

This section lists the matchups where STU performs worst and best over the last 30 days, sampled from top PRO players and smoothed with Bayesian WR to avoid noise.

Star Powers, Gadgets and Hypercharge

To get the most out of STU in the current meta, prioritize upgrades by synergy with their kit, not by gem cost. Star powers, gadgets and hypercharge change tiers depending on the meta, so the upgrade priority is dynamic.

As a general rule, the first profitable upgrade for STU is usually the star power with the highest pick rate in PRO tournaments, followed by the gadget that best fits their role (lane, support, or pick). Hypercharge, when it exists, comes last because it costs more Coins and Power Points and only triggers with a full super bar.

By game mode, STU performs best in Brawl Ball, with a 65.2% win rate over 2,343 battles — the mode with the most recorded sample for this brawler. That makes Brawl Ball the context where their performance is most reliable and where investing in upgrades pays off most clearly.

Beyond the immediate meta, the upgrade path for STU should prioritize what moves the win rate needle the most: power 11 before gears, first star power before second, primary gadget before any hypercharge. Hypercharges cost a lot of coins and power points and only activate with a full super bar, so their real priority drops toward the end of the checklist.

Weekly meta analysis

Over the last 7 days, STU's win rate moved from 58.9% to 68.8%, a climb of +9.9 points versus the previous half of the window. Since each half clears the 3-battle minimum, that move isn't noise: it reflects the meta shifting in STU's favor, usually from a rotation of maps or modes where they perform better.

Compared with the rest of the roster, that move puts STU climbing faster than 95% of brawlers with a measurable trend this week — they're at the top end of the risers. When a brawler lands in that band it's often a good moment to invest in their upgrades before a possible nerf arrives.

Every percentage on the STU page comes from real battles played by the world's top players, aggregated with statistical smoothing and recomputed every six hours.
