Nickname for Tobias

Been crushing on [name]Tobias[/name]. Not sure if there really is any nickname for [name]Tobias[/name] other than “[name]Toby[/name]” (what with that “as” ending…), but if anyone could think of one, it would be you berries! I like the sound of [name]Tobias[/name], but not really [name]Toby[/name]? Maybe I should go with a different name ending in -ias instead? Any suggestions?

It’s Tovia in Hebrew, so [name]Tov[/name]? [name]Tovi[/name]?

Or, as a stretch, Tolly?

[name]How[/name] about [name]Obie[/name]?
