Well, the strongest stuff I know of is two-part epoxy. Seems much stronger than super-glue to me and plus it won't dry up in the bottle after a month or so. I have a set of two bottles I bought at the hardware store over five years ago I'm still using. 

Gator Grip Glue is another option, it's not as strong but it does have a little flex to it. So if you bump a figure it will 'give' a little instead of breaking off.

Yeah, just to elaborate on what GM already said, drill a small hole in the figure's heel, another in the base, and then stick a small piece of wire in there. I use a cut piece off a paper clip, cheap and easy to find. I tend to cement the piece in the heel but leave the part stuck in the base free so I can remove the figures for transport, cleaning, etc. 

If you just cement the figure directly to the base it's only a tiny point of contact and I find them ripping off or falling over. The pin gives the figure some support there. 

 Thanks, I have done this in the past but want to use a glue on this resin base.

thanks,

I do not want to drill into the resin base.  Any suggestions for an adhesive?

thanks,

It'sisead if you can get a pin into the bottom of one of his feet.
