Imperial Fists successor chapter review (please help)

If I need to change anything to make it not a Mary sue, tell me (or just minor details that would be more lore logical)

Name: Knight’s Titanicus

Motto: No Mercy, No Step Back, No Brother Lost!

Homeworld: Anvillus II (Segmentum Ultima)

Fortress Monastery: Titanforge

Founding chapter: Imperial fists

Founding: Unknown (suspected to be second founding)

Codex Compliant: mostly

Chapter Master: Lord Titanicus Aurum “The Corpse”

Notes of intrest: See the emperor as a god (slightly less then red scorpion and black Templar levels) codex astartes is used for structure, tactics inside are often ignored

due to this legion being one of few chapters (I think) that are situated on a Forge World, this chapter has greater access to more heavy equipment, being one of very few chapters to have its first company totally wearing terminator armor. Company’s 2-9 wear the Gravis armor, and the tenth company wears the tacticus armor with Phobos servos (used to just use regular tacticus, too many neophytes died, they got sick of it). They are on extremely good terms with the Adeptus Mechanicus. The chapter fights like “the walking wall” of the Imperium. The chapter has 71 dreadnoughts however, layed out where the first company gets 8 dreadnoughts in active service, 2nd-9th companies get 7 active dreadnoughts. 13 dreadnoughts from across the chapter as a whole are always under mainatainace (the 71st will be mentioned soon). The chapters dreadnoughts are unusually active, and are extremely slow to suffer the physical and mental effects of being a dreadnought, it is guessed that a flaw in the gene seed, or rituals of faith to the emperor, and frequent visits to words for parades may help the dreadnoughts. One notable dreadnought, Lord Titanicus Aurum “The Corpse” (71st dreadnought for those who were wondering) is a Leviathan Dreadnought who is referee to as “the corpse” because no one knows how the fuck he is still alive. He attributes it to the many holy relics in him, and his faith in the God emperor. his sarcophagus has been unable to be opened, so it is assumed that the weapon burnout sealed it shut and burned away his body, and may have created a “thousand sons” type of situation, due to the holy relics not letting him die. He is subject to constant inquisition checks for heresy.

(I like leviathan dreadnoughts if you can’t tell)
