Update: Yes they are, he confirmed it.
I'm sure you all know about the new Madness series, the "Deimos' Adventures"-series. A new non-canon series about Deimos and also listed in the non-canon-section on Krinkels.net.
Cool I thought, but after rewatching it, I noticed that these two animations are different from other non-canon animations.
Like the obvious connections to the canon series: Deimos scars or burns from his injuries from MC 9 or the Flashbacks in SACRIFICE.fla. The normal non-canon animations, for example the Incidents, never have references to the canon story. The series is the only one with references.
Also, I if you paid attention, you will notice that, the series has the same creativity level as the canon series. Bringing in new things, instead using old stuff.
But then I thought, I was overthinking this topic, till Krinkels made a new Newgrounds post and I saw this:
Has Krinkels indirectly confirmed that Deimos' Adventures are canon? What do you think?
I feel like this is even more confirmed with the release of "POWERLESS.FLA" as there are even more connections to the main storyline now. I definitely think it's supposed to be canon, and I really hope it is because this mini-series is fantastic.
