Fourth Kind (I)
Fourth Kind is a Pro Hero who is always willing to lend a helping hand. His quirk, Quad Arms, not only gave him two additional arms but also increases his strength. He values guts and being chivalrous above all else.
Fourth Kind has two played abilities and one continuous ability. His continuous ability makes it so the fourth card he plays during the Combat Phase gets minus four difficulty and if it is an attack, it gets plus four damage. This means his fourth card each turn will ignore progressive difficulty and get minus one to its printed difficulty! This is an incredibly strong ability, literally stronger if your fourth card is an attack.
His second ability is an Enhance that is only playable once per game and on your turn. It makes your rival commit four foundations if they have six or more foundations. This means his rival will have fewer options and resources to work with on the turn he uses this ability.
Fourth Kind's final ability is a Response ability that requires him to commit and triggers after he blocks with an attack. It lets him add the block back to his hand. This means that as long as you hold on to one block, it will really be two blocks thanks to this Response ability.
