You have a nice SCP fanfiction/novel going. Only thing i dont like is the "cant teleport because its hot" thingy. Apart from this, your ff is good, good writing/gramma. Some more SCP interactions would be interesting to see, not fighting, just interacting with our mc and maybe helping him or him helping them in some way. SCP's which could be an interesting additon might be (all of them could power up our mc in someways but are also compatible with the flesh which hates, i think) SCP-658 the botfly parasite SCP-027 Vermin god lol SCP-253 Plaque Cancer SCP-354 Red Pool maybe it is blood and he can command it and the things on the other side (might be too op then) (i have more ideas but my phone is dead any second now) some scp which let him grow "flesh indefently" and maybe another which eats or burns this extra flesh but in exchange gives our mc minor fire control or immuntiy etc. There are many which could help our mc but still keep in line with his powers. Thanks for the chapter.
