Tien's partner-in-crime, EX Chiaotzu PUR is willing to sacrifice anything to protect his best friend--Even himself. This was seen in the Saiyan Saga Z when he self-destructed himself and Nappato save Tien and the others.
However, the Self-Destruct move is a hit or miss in. While it can have a huge impact on the outcome of a Match, waiting for a Fighter to reach low enough Health only to sacrifice them holds quite a risk and in this case, doesn’t always guarantee an Enemy kill.
Strengths
Self-Destruct
His toolkit has a consistent focus on increasing Self-Destruct Damage, especially when paired with Tien.
In addition to this, recent balance changes granted him improved stats and a better Z-Ability that significantly increases the overall Damage of Fighters with Self-Destruct.
The two major downsides of lacking Tags are bad Synergy and poor Equips, and EX Chiaotzu PUR has to suffer from both.
This makes him less viable because there’s less to support his poor stats.
Guarantees
While he is one of the few Self-Destruct Fighters in the game, it isn’t a Move that guarantees killing the Enemy unless it is used by an already quite powerful Fighter.
EX Chiaotzu PUR is not one of them, so his sacrifice may be wasted in PVP.
Team Synergy
Super Warrior
The Super Warrior Tag has almost no PVP viability at the moment, so EX Chiaotzu PUR is pretty much locked in with EX Tien YEL since both their Unique Abilities compliment each other.
A Self-Destruct Team with SP Majin Vegeta RED, SP Android #16 GRN, and EX Chiaotzu PUR as its core members is a bit of a gag Team, but it’s quite powerful and intimidating nonetheless.
