The shell bone script of character Bizarre is
which is similar to the second small seal script above, but there is a minor difference: the top of small seal script is character Me Self (己), but the top of the simplified song typeface is character Already (已). The difference is so small that you may not be able to notice, which is a mistake. But I don't discuss this topic here.
By the way, 异 is not formal character in traditional Chinese character. The simplified song typeface just uses 异 to replace the 異, not merge the two into one. They have similar meaning but not exactly the same.
Its Pinyin is Yi4.
