Which Pokemon has the most weaknesses in inverse battles?

Question

In the gen 6 games there's an npc who allows you do an inverse battle where type match-ups are reversed (i.e. Bug becomes weak to fighting but resists fire etc.) So during an inverse battle, which Pokemon has the most weaknesses?

Meaning?

Answer 1

By looking at the Dual-type chart and counting the resistances/immunities of the Part-Steel-types (the type with the most resistances), I can deduce that the mons with the most weaknesses in Inverse Battles are the Magnemite-line and the Honedge-line with 12 weaknesses each.

Also, Normal/Steel has the same number of weaknesses as those listed above.

Also, here are the ones with one weakness in the same scenario:
Normal/- is weak to Ghost.
Ice/- is weak to itself.
Psychic/Dark is weak to Psychic.
Water/Ice with Water Absorb is only 4x weak to ICE.
