He can be a dive character with his parkour/frerunning/grappling hook movement, he can be tanky with auto-dodges, he can be a melee powerhouse like a second iron fist, he can be a ranged character with his ricocheting perfect aimed billy club escrima sticks, he could even be a hybrid-dps-strategist using his sonar sense to mark enemies and reveal enemy health/armour/ult charge to team-mates.
He could even have abilities to autoamtically know if someone is aiming at him and from where as he has his sonar sense, pair that with a dodge move and he can be an anti sniper.
Or they could use his movement to make him an anti-flyer character, locking on to fliers and swinging up to force ranged fliers to engage in melee, which is something we need more of as we get more fliers.
