Here's a few of the most notable other Bizarro creations!
Bizarro Supergirlgiant Supergirl reprint!
...but got lucky and was able to beat them anyway, and this Bizarro Krypto was destroyed, but there would be more versions in the future.
This story was also reprinted in Superboy #138 (May-June, 1967).
Bizarro Legion of Super-Heroes
This Bizarro Superboy created his own Legion of Stupor-Bizarros, making imperfect duplicates of Brainiac 5, Lightning Lad, Saturn Girl, Chameleon Boy and Invisible Kid...
Thankfully, this team only appeared once, in Adventure Comics #329 (February, 1965 by Jerry Siegel and Jim Mooney) in "The Bizarro Legion", though the story was reprinted in Best of DC #57 of February, 1985 and in the Legion of Super-Heroes Archive #4 of 1994.
It's only fair that the Legion featured Bizarros in an issue, as they took over the spot Bizarros held there from Adventure Comics #285 of June, 1961 to Adventure Comics #299 of August, 1962.
Best of all, the Bizarro Adventures series can be found in Superman: Tales of Bizarro World tradepaperback of 2000, with the Bizarro story from Superman's Pal Jimmy Olsen #80 being in the Superman: The Amazing Transformation of Jimmy Olsen tradepaperback of 2007.
Well, Mr. Mxyzptlk got the treatment, with Bizarro Kltpzyxm, who first appeared in Adventure Comics #286 (July, 1961 by Jerry Siegel and John Forte), who would say his name forward to go away (since he does the opposite of his doppleganger, and wants to go away, by saying his name forwards instead of backwards). He also appeared in Adventure Comics #287, #288, #292 and #294.
Titano got the Bizarro treatment, with Adventure Comics #295 (April, 1962 by Jerry Siegel and John Forte) in the story of "The Kookie Super-Ape", where Bizarro No. 1 created Bizarro Titano to wrestle with Bizarro Lois Lane so she could be defeated and not become wrestling champion (and thus, by winning, be exiled from Bizarro World....).
Bizarro Titano won the match by running away!
Ah, the wonderful Bizarro logic....in Bizarro Titano's only appearance.
