Back in the 1980's, terms like "voltage" still had the aura of "high tech" or "mysterious power" about them.
This show and a few others were the more extreme in use of pointed chins. Late 1980's and early 1990's anime continued the trend with pointy chins, but without the overly thin faces - Bubblegum Crisis being one example.
