Rosa thrives in Showdown. When using her Super, she can take on Brawlers like Bull who would normally defeat her in a close-quarters fight by utilizing the enormous damage reduction provided by her Super and still expect to come out on top. Rosa is also an excellent bush-camper when her Plant Life first Star Power is equipped. With Plant Life, she can hide in bushes where she heals and can attack nearby enemies while healing.
In Brawl Ball, you can use her Super before collecting the ball and then walk the ball into the goal to score. Her high health, above-average movement speed and ability to perform team-wipes with her Super make her very viable in this mode. However, be wary while walking the ball into the goal because many Brawlers have stuns, pulls, pushbacks, or knockbacks that can prevent you from scoring.
Rosa and El Primo have the same movement speed, but Rosa's range is slightly longer and wider, meaning that she’s able to escape and attack him while being out of his range. This technique can also be used when fighting opposing Rosas. Walk away from the Rosa while also attacking towards them, and they should walk into your punches. You should also avoid attacking when the Rosa uses her shield, as you’ll waste ammo and deal little to no damage to the Rosa.
Rosa’s Super has an extremely high damage reduction but has a rather short duration, so make sure not to overestimate its power, especially if you’re on low health. However, if you’re in a tough situation, immediately activate her Super so you can attack the enemy with ease while taking little to no damage, which can prevent an inadvertent loss. This gives you a better chance of staying alive or even defeating the enemy.
If she can surprise the other team (in any mode) while her Super is active, Rosa can continuously chain Supers, wiping the enemy team. However, remember the shield doesn’t make her invincible and it’s possible for defeat against a high-damaging team composition containing the likes of Nani or Griff.
Rosa's Plant Life Star Power allows her to heal 200 health per second while in a bush. Be sure to use this when fighting another Rosa which allows her to out-heal the enemy while still damaging them. She can even use Plant Life to counter tick damage such as Crow's poison.
It is advisable to use Rosa’s Plant Life Star Power on maps where there are many bushes and her Thorny Gloves Star Power on maps where there are less bushes.
In Duo Showdown, be sure to have a team composition that can cover Rosa's weakness of range. The most obvious choices are any mid/long-ranged Brawlers, these include Brock, Piper, Colt, or even Carl in some maps.
Rosa’s Grow Light Gadget can be used to add and connect bushes to make it easier for her to ambush enemies. When paired with her Plant Life Star Power, Rosa can use her Grow Light Gadget to passively heal herself when wounded in battle.
Rosa's Unfriendly Bushes Gadget can be used to briefly reveal all enemies hiding in bushes due to it dealing 100 damage at an indefinite range. Combined with a Gears|Speed Gear, Rosa can locate and engage the enemy quickly due to the enemy being slowed down and the speed boost from the Speed Gear.
Rosa is a tank, so she counters assassins under the right circumstances. With the exception of Edgar, you can usually engage other assassins at 1-tile distance and defeat them, so always maintain close quarters with them. In the case of Edgar, keep a few tiles distance because he out-damages Rosa while she out-ranges him.
Rosa is easily countered by control Brawlers, which are mid-range Brawlers that can pushback, knockback, pull, slow, or stun with their Supers, have a high damage output and usually low health, such as Emz and Spike. It’s best to avoid these Brawlers unless you know the odds are in your favor.
Rosa excels in 3v3 modes, especially in Gem Grab and Hot Zone. She works well as a Gem carrier in Gem Grab because of her fast movement speed, healing abilities, high damage output, and high health. She can also be used to protect and tank shots for allied Gem carriers. Because she excels in close-quarters combat but out-ranges the other melee Brawlers in the game, she’s also a decent choice for Hot Zone. She’s also a decent pick for Siege and Heist due to her high health, extreme survivability, and high damage output.
