Hello everyone and welcome to my 154th analysis, this time featuring Galante Jr.
Jr. has the best skills of his parents: an AOE Possession and a 100% Stamina drain. Furthermore, his AOE Possession drains 50% Stamina from its targets, and he has a single target Stun as well. The only problems with Jr. are that his Stamina drain weirdly costs 139 Stamina and his Speed is lower than 3465.

Movesets:
-Get Shifty
-Hysterical Fans/Swagger Leak
-Trendy Hit
-Remember Me
Runes: 3 Speed

Get Shifty drains 50% Stamina from all targets and Possesses them, making it a must have move. Hysterical Fans drains all the Stamina from the target at the cost of Jr.'s own Stamina, but if you find denying yourself to be undesirable, Swagger Leak works very nicely with Get Shifty: if both land on all enemies, they will likely be denied for 2 turns, thanks to the initial 50% Stamina drain, the Stamina cost of the move they'll use while Possessed, and the Stamina Leak. Trendy Hit is a single target Stun and Remember Me has a chance to Possess all enemies hit. 3 Speed is necessary on a denier.

Teammates: Jr. can fit on any team.

Countering Galante Jr.: Your best bet is Scarr the Outcast since Jr. has a vast array of deny options, and Bulwark is perfect to counter that-if he uses Hysterical Fans on you, he will deny himself too. His father is faster than Jr. and can drain all of his Stamina. His primary deny method is Possession, so bringing Possession-immune monsters against Jr. is a good idea.

@Orkan-Öztrak Because of the high stamina cost, Hysterical Fans is way too unreliable, because you will sacrifice a turn to deny only 1 monster. With that , the AOE Stamina Leak is a way better skill, because not only it doesn't cost too much stamina, but you can combine with Get Shifty to deny the enemies for 2 turns.

@Max-Pinheiro The ability to deny anything, even if it costs you a turn, is very valuable since against things like Generals, VIPs and soon Artifacts, Stamina leak may not be worth it. True, it may allow for a 2 turn deny, but for this combo to work, both AOEs need to land on all enemies twice, which, as you should know, is not too high of a possibility. I will list it as an option though because it definitely has merit.
