Constantine

[Drunk Monk]

There was this live action show, which was part of the Arrowverse, as is Legends. That only ran one season but it was NBC and it should've been CW where the bulk of the Arrowverse thrives. There was also an installment of the DCAMU - he had one stand-alone two-part film, and I assume he appears throughout the DCAMU because that's how MUs work, right? 

Keanu is cashing out on all his old franchises.
