Botzu's Quick Evaluation
+ Talent: Decent on-deploy AOE damage and applies the [Fragile] debuff that boosts damage taken by enemies
+ Cheap to deploy and develop
+ Useful in bursting down high HP bosses, and for stages with lowered deploy limits
- The long redeployment time will only allow one or two talent uses on most maps.
- Doesn't attack normally
Operator Overview
Another casualty of “Master Closure’s” campaign to brainwash Rhodes Island’s robots into adoring her unconditionally, Thermal-EX is a 1★ Robot Specialist who specializes in, well… blowing himself the hell up.
Like the other Robots in Arknights, Thermal-EX works a little differently from human Operators. Robots don’t count toward the Unit Limit when deployed, but they have extremely long redeployment timers. In addition, they have no Skills and cannot promote; their power comes primarily from their Talents. Thermal-EX’s Talent is called Delayed Detonation. I think you can see where this is heading.
Delayed Detonation causes Thermal-EX to charge up for a few seconds and then explode, damaging all enemies around him and inflicting the Fragile debuff on anything that survives. After exploding, Thermal-EX is forcibly retreated from the battlefield. The damage is nice, but the real benefit here is the Fragile debuff, which increases the damage taken by its victims. Detonating Thermal-EX on a tough boss or a wave of difficult enemies makes it much easier for your other Operators to burn them down quickly.
Even for a Robot unit, Thermal-EX can be a little situational. Robots are often used as decoys for enemy attacks because they don’t count towards the Unit Limit, but since Thermal-EX doesn’t stick around, he can’t always fill that role in the same way (though Thermal-EX’s high DEF does allow him to soak a hit or two before he, uh, “retreats”). His long redeployment timer also limits the number of detonations you can get on a given stage. However, the Fragile debuff is extremely powerful (though keep in mind it doesn’t stack with other Fragile buffs from Operators), and it can tip the balance if you’re struggling on a particular stage. Considering how cheap Thermal-EX is to max out, this cheerful little ro-bomb is certainly worth the investment.
Newbie Tier List Explanation
He's only in this Archetype because of developer classification. Can be used for his on-deploy debuff, but most players will not need or desire to try to make him work, and will prefer to use the team slot for a more complete Operator.

- The [Fragile] effect from Talent has an 8s duration.

Profile
As a new model, Thermal-EX's boasts a unique and aggressive appearance that can be somewhat intimidating. But he doesn't mind. After all, anyone can hear Thermal-EX's loud and warm greetings from a distance long before he's clearly visible. However, it seems like his vocabulary has been excessively bloated with words pertaining to 'hot'...

Increase Trust to 100.'Unexpectedly, even some introverted and normally unsociable Operators are willing to spend the day with him and listen to his endless prattling... but this too is good. I've decided to scrap my plan to reconfigure his language prioritization logic.' That's what Closure said.
