I'm trying to figure out how anyone would think it meant Super Monster considering TAC stands for Terrible-Monster Attacking Crew. It's right there in their name. Was this a fansub name thing?
Ignoring Ultra Q: Dark Fantasy Ace was the last Ultra series to be fansubbed (unless crabsticks don't count in which case Cosmos is still in limbo and nobody bothered with Return of Ultraman). Chou means Super in Japanese and I remember seeing the Malaysian dubs which called them Super Monsters, everyone based it on that translation.
I keep hearing how terrible Taro is
Taro isn't so much terrible as it is really damn weird. Hell, the first episode starts off with one of Yapool's chouju being munched on by a vagina dentata flower. As a long time Ultrafan I'll give you several non-spoiler heads up on what you're in on.
-Thanks to the Oil Crisis of 1973 Taro had to cheapen its effects by a lot.
-Taro really REALLY loves pyrotechnic spamming in its monsters.
-Supposedly Taro was going to be only 49 episodes but Leo fell behind production so an extra four were made. Kind of ironic since Dorobon is a more fitting final boss than Samekujira and Valky Seijin- Oh I'm sorry for some reason they call Samekujira Shark Whale! CALL THE MONSTER BY ITS FUCKING NAME! But yeah, X showed a baby version of that, final ep has the adult.
-Taro's color timer had a habit of going off way sooner than in other Ultra shows, if you feel the tension is forced it's not just you.
-Eleking returns as a ghost in one ep, I have to say this because it looks very dilapidated and I think it works well for the whole undead vibe going for it. I bring this up because Mephilas Seijin (same species different member) and Yapool return and their costumes.... Took liberties and don't have the same undead vibe going.
-There is another fart monster in this, it is not the worst one of the series. That one goes to Okariyan, probably my least favorite monster in the franchise. It's the one with the long ear probes and resembles Tochiro from Captain Harlock.
https://ultra.fandom.com/wiki/Okariyan -The Murora two parter has a backstory to it that inspires the second half of Ultraman Mebius and a famicom game called Ultraman Club. You will know it when you see it.
-The Birdon three parter is legit good. The Temperor Seijin two parter is treated similarly although it is similar to the Hipporit two parter (aka the one Father of Ultra first appeared in) which was beloved by fans.
-The famous Tyrant episode is a love or hate episode and partially a clipshow. Most fans justify this as to proclaim why Taro was the most powerful Ultra in the showa era (and ignoring Glitter Mode Tiga and Gaia Supreme probably the most powerful Ultra of the 20th century). I remember back in the day how bigly he was fanwanked on Toho Kingdom (although nobody ever topped Wing Gundam Zero, not even Unicron and Galactus).
-There's a family of bird monsters called the Raidron, these things inspired space herd monster ideas seen in 80, Mebius, and Ultra Galaxy NEO.
-I expect your least favorite monster might either be Rodera or Mukadendar (the latter reappears in Ultraman Mebius).
-There is a monster named Elegia that was a normal bird turned kaiju, this plotline is reused in Ultraman Tiga.
