Long List of Canon Series

Released Series
The KyBer Leger Show (obviously)

Supre M8 (Up until The KyBer Leger Show S1E5, it was not, but the reintroduction of Supre M8's character establishes it as canon now)

Unreleased Series (these are in the works)
Guardian (During the events of The KyBer Leger Show Season 2, Guardian splits off from the group, to save Dimension 61919-S from Mr. Computer, as well as to hunt down the mysterious new threat, Lord Tenebrae.)

Behind the Memetahias (A young Memetahias studies everything to ever exist, discovering many new things, whilst fighting in the war against the Raeditors and the Forrchannors with friend and colleague-turned rival, Professor Lordius.)

Brains and Brawn (During the events of The KyBer Leger Show Season 2, Zombie Guy and Strong Kong deal with an interdimensional mafia, the Shadow Mafia, lead by the all powerful mob boss Mr. Obscurum.)

Hunter Joe (A Hunter Joe origin story, where Hunter Joe fights in his planet's civil war.)

Sort of Canon
Plight the Paper Knight (I say sort of canon because the series wasn't made by KyBer Leger, however, Supre M8 appears to be aware of the series' existence, and Plight is shown to exist)
