The only anime I've seen with over 1000 ratings from users are Jojo's, JJK, One Piece and AOT. Even huge animes like DBZ, Naruto and Bleach don't have 1000 ratings. For reference Invincible and the Boys have over 7000 user ratings while having a similar amount of overall ratings on IMDB.
How many fucking times does it need to be said that Conquest is the 2nd strongest Viltrumite, Thaedus is weaker and less durable, Conquest number 2, Thaedus number 3-5 depending on where you scale current Mark and Nolan.
And the 2nd point is pretty self explanatory.
1.) Omni-Man vs Invincible (Invincible S1)
2.) Zuko vs Azula (ATLA S3)
3.) Gojo vs Sukuna (JJK chapters 223-236)
4.) Daredevil vs Poindexter vs Fisk (DD S3)
All Might/Toshinori Yagi (Boku no Hero) vs Deborah Grayson (Invincible)
This is who's better written as a mentor figure/parent, not as a whole.
This version of Thragg is easily still an elite Viltrumite seeing how he was probably heading entire invasion forces on his own but he also remarks that Thaedus was the strongest of his crew, how strong is he and how does he fair against Thaedus, Conquest, Nolan and such.
