Twitch Streamer: Altrive is a twitch streamer, which requires you to talk with people. Altrive has advantage against all Charisma checks. Also, he is always Streaming at all times.

Streaming: Because Altrive is always streaming, some of his viewers may randomly join his stream. When Altrive's turn ends, he rolls a flat d20 to determine whether or not any fans join. If he rolls a 15 or above, he rolls a d4 to determine how many fans join. He also gains access to the bonus action Chat, Type 1.

The Main Character: Altrive is the main character. According to main character rules, this gives him the ability to use 3 actions per turn.

Joker From Persona 5: Altrive has the unwavering belief that he is Joker from the hit game Persona 5 (who happens to be 1-A on the Versus Wiki). It's not even a belief anymore, it's true. Due to this, he can use Joker's Neutral B.

Yiiking Out: Altrive is also Alex Eagleston. Alex also becomes a god in YIIK. Altrive can gain access to the ability LP Toss.

The Strongest Character in All of Fiction: Altrive is also Goku. This means that he can use the Kamehameha.

Izuku Midoriya: Altrive's impression of Deku is ridiculously good. It's so good that he can even use the Detroit Smash.

Greatest of All Time: Altrive is the greatest to ever do it. Because of this, if Altrive rolls a 1 on his attack roll, he automatically rerolls it and takes whatever the new roll is.

Wholesome: Altrive is so wholesome that nobody can bring themselves to hurt him. At the start of battle, every attack against Altrive has disadvantage for one turn.

Gamer Reactions: Altrive has been playing games for a pretty long time. He also played Elden Ring that one time. Due to this, Altrive has resistance against all non-magical physical attacks.

Erm...Awkward: When the opponent hits Altrive with a critical hit, Altrive needs to change the odds in his favor because it would be awkward if he lost. If the opponent rolls a critical hit, Altrive can resist all damage received after the critical hit for one turn.

Down Bad: Like every main character, Altrive is not invincible. When Altrive sees an image of Opila Bird, he is stunned for 1 turn (this can only happen once per battle).

Recorder Beatbox: Altrive pulls out a recorder and starts beatboxing on the recorder. The opponent is automatically charmed and must roll a Wisdom saving throw at the start of their turn (DC 20).

Detroit Smash: Melee Attack: +10 to hit, reach 5 ft., 1 target. Hit: 36 (8d8 + 3) bludgeoning damage.

LP Toss: Ranged Weapon Attack: +15 to hit, reach 15 ft., 5 targets. Hit: 22 (4d6 + 8) bludgeoning damage. 

Joker's Neutral B: Ranged Weapon Attack: +15 to hit, reach 30 ft., 1 target. Hit: 43 (8d8 + 8) piercing damage.

Kamehameha: Ranged Weapon Attack: +15 to hit, reach 50 ft., 1 target. Hit: 43 (8d8+ 8) fire damage.

Chat, Type 1: As a bonus action, Altrive can tell his chat to type 1 if they want him to win. Altrive rolls a flat d20 and if he rolls a 13 or higher, he gains advantage on his next attack roll.

Who needs reactions when you have actions?

Conqueror's Haki: Altrive is kinda like Luffy from One Piece. Any creature within 100 ft of Altrive must make a Constitution saving throw (DC 16). Creatures that succeed are knocked prone. Creatures that fail are rendered unconscious. This can only be used once per battle.

We Do a Little Trolling: If there's one thing Altrive can do, it's troll. So, he asks his opponents to type ":tf:" in his chat. Any creature in combat with Altrive must roll a Charisma saving throw (DC 20). On a failed save, creatures take 50 (10d10) psychic damage, while successful saves only take half as much damage.
