The second page of a reverse image search leads me to this Deviant Art page, where it's made clear that this is fan art. (A lot of fan edits can look reasonably professional. For example, I know of someone on YouTube who includes a lot of scenes in her AMVs which she creates with Photoshop or the such. As an example, this Fullmetal Alchemist AMV features a number of with Hawkeye and Mustang that are non-canon, and which the creator states as such on her Tumblr blog.)
However, since it's still interesting to look at whether or not a cross-over exists, I'll take a look at that as well. It doesn't look like there's an anime starring all four, at least in that a search for any cross-over spin-offs doesn't generate anything "official". As I don't follow any of these series, this may have been insufficient.
For what it's worth, I searched for one piece spin-off dragon ball z naruto bleach
. However, one piece spin-off dragon ball z
did generate this one-chapter collaboration involving both series and Toriko, so it can't be that my search terms are completely off. Replacing spin-off
with collaboration
still yields no useful, official results. Moreover, when I put the names of the series in quotation marks, all I ended up with on the first couple pages were either references to the Toriko collaboration or people comparing all four series.
