The semicolon could have been intended to be a colon (explainable on both mainstream US and UK keyboards by not hitting the shift-key) as a list-introducer of weaknesses. The first item is 'fear' but no further items emerge as it wanders back to the early aim of the sentence's tale-telling.
As a total mis-hit, it is not so obvious. It's entirely on the other side from A and S and even the F, for me and many others. The usual error is in conjunction with the L-key (instead of/in addition to). Laptop keyboards and other national variants sometimes have other positions that I'd grant were possibly being used, so one cannot that rule out. Perhaps even adjacent to the space-bar you would use in that sequence. On balance, I still say it's odd enough for comment.
There is also a definite style used by the author
s of that piece that
is over-commaed if you dip in randomly.
Bubbles realizes his identity, but by that point, Octi has grown to a gigantic size, and he goes to destroy Townsville, or according to HIM's words, "the world."
"Comma but", perhaps misplaced given the next comma. "Comma and" . "Comma or", again perhaps misplaced given the next comma. Possibly a word or two that needn't be there or should be there that isn't.
Trivially editing, I would suggest more accurate breaking out of the two side-clauses (by that point / according to HIM's words) then further reduce the comma-conjunction superfluity (not bad, just pointedly overused in the original case) by splitting the sentence to prevent the list-like comma and aside(-of-an-aside-of-an-aside)-like comma being mistaken from each other. You can even easily avoid a "never start a sentence with a conjunction" argument in one case. Perhaps with the other too, although it's not a problem if it's not "And then I... And then I... And then I...". Capitalisation and exclamation-punctuation of "The world!" is an option that I've left unapplied but purists who also know the vocal emphasis and tone given in the source material might consider that viable.

I'm far from perfect, so I have no right to edit the text myself just because I flash a tatty old Grammar Nazi identity document that's probably rightfully been recalled. There is, though, a seeming pattern to narrative summaries such as this that pervades fan-wikias but
tends to be stomped on in the mother-of-all-Wikis for readability reasons. That makes me think it's a point worth thinking about, even if I do nothing about it myself.
(I was originally more worried that the jacket and belt and buckle were described in detail and yet without any reference to being in the typical Santa Claus style. Maybe this is just me, but if the chatacter isn't intentionally Satan/Santa with additional lobster/drag elements then the animators have got
differently weird minds than I imagined.)
