The DCU has been in full swing for two years now, but it sounds like James Gunn still needs to make some decisions about what exactly is canon from The Suicide Squad and Blue Beetle.
The DCU officially began with Creature Commandos in late 2024, though elements of The Suicide Squad and Blue Beetle – which are both part of the old DCEU – are still considered canon. Gunn has previously said The Suicide Squad is like an "imperfect memory" and Blue Beetle is the first canon character of the DCU.
