Freezo's former familiar. Previously assumed to be a Feydragon (an interpretation of the pseudodragon), he is actually "some kind of Dragonborn thing". Bushu speaks with a South African accent and hates Freezo, but while working as his familiar usually did what Freezo asked, if begrudgingly. He is pretty good friends with the other Dragon Friends.
Bushu is legally distinct from Mushu from Mulan.
Season 2[]
Freezo casts find familiar to summon Bushu. Bushu is antagonistic to Freezo throughout the campaign, often asking why Freezo can't do these things himself. (Unlike a standard familiar, which once summoned remains with their master until they die, Bushu mostly resides in his home in the Feywild and can be summoned at will by Freezo.)
Season 3[]
Freezo summons Bushu to help after a helicopter carrying the Dragon Friends is shot down. Bushu explains the predicament succinctly with the quote:
"Yea, I can fly. You're fucked!"
While waiting to go up to Freeside, the Friends play a video game called "Tomb of Annihilation" in which people level up and familiars are freed. Try not to think of the canonical repercussions of this too much.
Tomb of Annihilation[]
Bushu is first summoned by Freezo in The Pride of Candlekeep (TOA 1.05), explaining that all of Baldur's Gate copied his accent because they all said it sounded so cool (implying a representative of Baldur's Gate went on exchange to the Feywild and came back with a different voice). After verifying the people on the pirate ship are all from Baldur's Gate, he disappears.
In the second season of Tomb of Annihilation, Bushu is primarily summoned to trigger potential traps (TOA 2.02, TOA 2.04 and TOA 2.08) or sniff an object to tell whether it's magical or not (this being the prime reason why the party could last without the Detect Magic spell to detect magic).
In 2.08, after previously finding himself enjoying a Singapore Sling in the Plane of Cocktails, Freezo and Bushu have a long overdue performance review after which Freezo proposes a deal: if Bushu hits and triggers a specific lever, Freezo will set him free. After pinky swearing, brokering a forgiveness package, some other stuff, and then completing the task, Bushu gets emotional and leaves forever.
Season 4[]
When jumping around the Nine Known Worlds, the Dragon Friends meet the freed Bushu in the Feywild. They spend time at Bushu's house before going to the fairy court, which Bushu hopes to become a member of. Although he initially (yet only partially) succeeds in preventing Freezo from embarrassing him, the Dragon Friends are ambushed and captured by Jayne Steyer and his men. He aids the Friends in trying to rescue Oberon before the latter's ejaculated portal closes just after he entered, separating him from the Friends (except for Baston and Bassbass Wihouveberry).
Beef Babes[]
Bushu comes clean and reveals he is not a Feydragon, as previously stated, but is in fact a Dragonborn. He joins Freezo and Kit Gingerson as they assist Bethanee Smiles on her Godsquest as the Beef Babes.
Near the end of the second season of Beef Babes, Bushu becomes a casualty of Michael Hing's go at playing NPC's. Luckily, the Beef Babes are able to resurrect him with a wish granted by an infernal contract. In exchange for this wish they are required to kill the Dragon Friends.
