Tira has two "stances": jolly and gloomy. In jolly, her moves generally aren't as fast/safe, but have a bit more emphasis on range, her damage is a lot lower, and she only has two moves that are self-damaging; she generally plays a lot more passively and keep-awayish here. In gloomy, her moves are generally faster/safer, her damage is a lot higher, and she has a larger variety of attacks that hurt herself; gloomy Tira likes to be aggressive as fuck. Transitioning between the two is a bitch, with two exceptions: she automatically shifts state at 40% health, and using her super while in jolly will force a switch to gloomy. Other than that, she has a bunch of moves that have varying degrees of success at switching states depending on if they whiff/hit/are blocked; what's especially aggravating is that it's generally much easier to randomly shift from gloomy to jolly than vice versa. What's even more aggravating is that the moves that can switch you from gloomy to jolly tend to be really good, while jolly only has one good move that might switch you to gloomy, but it has crap range.
